What's Wrong?

When I try to give a command on claude-cli I get API Error:500. Even for trivial commands such as "hello" I get this error
❯ hello
⎿  API Error: 500 {"type":"error","error":{"type":"api_error","message":"Internal server error"},"request_id":"req_011CYVBx3FZkoQH9cjp5B34t"}

What Should Happen?

My main request was for the claude to create a patch file for my project code
